The section 3 of the conveyer is hingedly connected to the intermediate section 2 as shown at 16 and is provided at its free end with hearing blocks 17 in which is journaled a roll 18. A transverse tie rod 19 connects the sides of the section 3 close to the roll 18. Endless belts 20 are mounted on the rolls 18 and 8 and the lower flights of these belts extend under a transverse rod 21 which connects the sides of the intermediate frame 2 between the roll 8 and the hinge connections 16. Another rod 22 connects the bearings 17 and has fingers 23 pivotally connected thereto and normally suspended therefrom. The roll 18 1s interposed between the rods 19 and 22 as shown in Figure 3.

' adjacent the centers of the sides thereof and the free ends of these braces are ttorltcd as at 29. Thus when the section 3 is swung upwardly relative to the section 2 it becomes possible to place the forked ends 29 of the braces astride the studs 26 where they will be retained against lateral displacement by the heads of the studs.

Pivotally mounted on the rod 21 close to the sides of the section 2 are ar'cuate racks 30 meshing with gears 31 secured to a transverse shaft 32 journaled in bearings 33 carried by the strips 25. A longitudinal groove 34 is formed in the convex face of each rack 30 and projecting into each of these grooves is a lug 35 extending from a guide block 36 extending laterally from the adjacent strip 25.

A hand wheel 37 is secured to the shaft 32 and constitutes a means whereby the shaft and its gears 31 can be rotated to raise or lower the racks 30. For the purpose of supporting the racks in raised positions, pins 38 are insertable through openings in the racks so as to bear downwardly on the strips 25. These pins can be connected to said strips by chains 39 or other suitable means.

Under normal conditions the conveyer is arranged as shown in Figure 1 with the sections 1, 2 and 3 substantially in alinement. 'One end portion of the section 1 bears downwardly on a portion of the print-- ing press D while the end section 3 rests upon the table B of the bronzing machine. When thus located the fingers 23 project into the feed opening 01'' the bronzing machine. As before stated the roll 7 is adapted to be driven by any suitable mechanism not shown. Thus as the printed sheets are de-- livered from the press they will travel with the endless belts 15 and be transferred from these belts to the belts 20 which. in turn. will direct the sheets along the lingers 23 into the bronzing machine.

Should it be desired to feed into the bronzing machine sheets that have been printed on some other press, a hoistof any pre'lerrial construction and which hasv been indicated generally at H in Figure 3 i.-= connected to the section 1 of the conveyer preferably at. a point adjacent the press D. 'lhis hoist is then used tor liii'ing one end portion of the section E so as to support it at. a desired distance above its normal, positiom Shall 32 is rotated by means of the hand wheel :57 and the gears 31 will cause the racks 30 to move upwardly after which the pins 233 can be inserted into the rack so as to hold them in raised position. This upward movement of the rack will cause the intermediate section 2 to swing upwardly to the position shown in Figure 2 so that the section 1 will thus be supported in a ubstaniialty hori zontal position away from the table I) o t the bronziug machine. The short end section I) is then swung upwardly by hand or in any other manner desired until the braces Q3 can be placed with their forked ends asiridc the studs 26. Consequently section 3 can be supported in an upwardly inclined position as shown in Figure 2. After the parts have thus been adjusted the operator ongaged in feeding sheets to the bronzing machine takes his position on the platform after which the stacks of paper can be placed on the table B. This can be done without disturbing the person on the platform because it is possible for the assistant who is arranging the bundles to stand at the back of the table and properly position the bundles thereon. As hercloil orc c:-;plaincd it has been necessary hcretolore to place these bundles on the table 13 from the side and this could. only be done by interrupting the work of the person feeding the sheets to the machine. By mounting the conveyer as described however, the feeding operation can continue uninterrupted and a considerable saving of time will result.

It will be noted that when the conveyer is elevated as shown in Figure 2 the slack in the belts 15 resulting from the relative movement of the sections 1 and 2 will be taken up by the shaft 4 which will come against and support the upper flights of the belts. Atthe same time the slack in the belts 20 will be taken up by the rod 21 which will engage the lower lights of the ti ti belts ill} as shown in Figure 2. Danger of the belts becoming displaced during the raising and lowering ot the elevator is thus reduced to the minimum.

Although the ends of the braces 28 have been shown and described as forked, it to be understood that, under some condi-- ticns they can be slotted instead.

lin the structure shown the sections of the conveyor are supported. substantially in alineinent when in use. This is not essential, lIlii'WLl (ilfl ll hen some types o'l'f press .2 are used with the bronzer the sections can be maintained out of alinenient While in use.

l l hat is claimed is:

'lthe con'ibination with a supporting structure, ot a conveyer including an inter mediate section hingedly connected to said structure, a main section hingedly connectec to one end portion of the intermediate tion, an end section hingedly connected to the intermediate section at a point between the ends o'l said intermediate section, a con-- veying; belt carried by the main and intermediate sections, a conveying; belt carried by the end and intermediate sections, said belt-s being movable in the same direction sinniltaneously, cooperating means upon the end and intermediate sections tor supporting the end section at an angle to the intermed 7 section, and cooperating means ripen tin intermediate section and the supporting strin-tnre tor adjusting the intermediate section anguiarly, thereby to elevate one end oi the end section and ot the main section relative to the supporting structure.

it conveyor including a main section, an end section, an intermediate section hinged at one end to the main section and at its other end to a support, said. intermediate section being; hingedly connected between its ends to one end oi the end section, endless conveying; belts carried by the end and intermediate sections, endless conveying; belts carried by the main and interiiiiediate sections, all oi said belts being movable in the same direction, and means for swinging the intermediate section about its point ott connection With its support, thereby to elevate simultaneously those end portions ot' the end and main sections connected to the intern'iediate section.
